Genus. Enchodus. 



Enchodus, sp. 



A small number of teeth, apj^arently belonging to the genus Encliodus, have 

 been found in the Upper Senonian beds characterized by the presence of Belemnites 

 mucronatus at Kopinge. The largest of the teeth is 0*015 m. in length, with a 

 diameter at the base of 0"003 m. The surface of the teeth is finely and regularly 

 striated longitudinally ; the tooth is compressed, and a sharp edge is produced 

 along each lateral margin. The teeth are broken off at the base, vphere they 

 have probably been anchylosed with the jaw. Other specimens, two-thirds the 

 size of the above, exhibit similar characters, one of them being especially well- 

 developed along the lateral margins, which extend in a knife-like process on each 

 side. 



The teeth are jDrobably those of Enchodus halocyon, Agassiz, {lewisiensis, Mantell) 

 (" Poiss. Foss.," vol. v., pt. i., p. 64, pi. xxv. c, figs. 1—16) ; but there is scarcely 

 sufficient preserved to satisfactorily determine the identity.

Genus. Bathysoma. Gen. nov. 



Body compressed and elevated ; head large ; snout prominent ; scapular arch 

 composed of bones of great length and thickness. 



Bathysoma liitkeni, Davis. 



(PI. XLVI., figs. 1-7.) 



A fine series of specimens from the Saltholm Limestone occur in the Museum 

 of the University of Lund and in the Mineralogical Museum of the University of 

 Copenhagen. They have all been obtained from Limhamn, in Scania. The fish 

 is compressed laterally; it reaches a length of about 0*10 m., and the height of 

 the body immediately behind the scapular arch is equal to four-fifths of the 

 length ; or, if the measurement be taken from the anterior extremity of the 

 mandible to the peduncle of the tail, the height of the body is equal to the length.
